However, we question how effectively it can actually protect you from airborne contagion. Sure, it may filter the air shooting out of that tiny ball-jointed wind cannon, but it isn't like you're sitting in a hermetically sealed bubble -- odds are at least one of your elbows is touching someone who is actively coughing up a swirling cloud of hot disease, enveloping you and everyone else in the row. This is arguably the first time in history that a plague mask would be the more practical option.
Various Infidelity-Busting Hidden Cameras
Yes, it just looks like a regular ol' clock -- that's the point. It wouldn't do you much good as a "catch your spouse banging the gardener" hidden camera otherwise.
There's a large enough consumer base of people willing to spend $600 to catch their spouses in the midst of an adulterous affair that an exhaustive market has sprung up to support the demand (see "panty swab," above). If you think your husband or wife is cheating on you, you can buy a variety of hidden cameras cunningly disguised as absurdly conspicuous household items to be suddenly displayed in several prominent rooms of your home without explanation. So for instance, if you think your significant other plans on smashing pelvises with a co-worker on a bearskin rug in front of a fireplace, that mantle clock will catch them dead in the act. Also, it looks like something a sea captain would keep in his cabin next to a picture of his dead mother, so if any of that applies to you, it could make a worthwhile purchase as well.
